Ok i was really going for something a child could wear. Something that Children could wear without their mothers freaking out about it getting dirty. I also wanted something that you couldnt look at and scream JOKER! because i was afraid that would be a costume giveaway, so i just incorporated some joker features, and ofcourse colors.

The Business suit is shown by the vest.
The almost clownish-ness is shown by the plaid.
The jokers famous tie, is shown instead by the little girls headband.
And the business shoes are turned into the maryjanes.
